What Is WhatsApp Business API?

WhatsApp API was launched to help medium to large companies that wanted to use WhatsApp to communicate with multiple customers at scale. WhatsApp Business API enables businesses to automate communications with automated replies, WhatsApp chatbots & interactive messages.


In short, WhatsApp Business API helps businesses to create a personalized communication flow that works best for their customers.

WhatsApp Business App

WhatsApp Business App & its WhatsApp Business Web extension are free-to-use apps aimed to help small business owners. It helps small businesses connect with customers and offer their products and services and support them through their journey. But it has limited capabilities and is not built for scale.

Features Of WhatsApp Business App

● Canned/quick replies

● Dedicated WhatsApp Business App

● Conversation labels

● Set away messages

● Dedicated business profile/hours

● No integration with other systems like Chatbot, CRM

● One person usage

How is WhatsApp API different from WhatsApp Business App?

  • WhatsApp API is built for businesses that want to scale. Since WhatsApp Business App is for small businesses, it does not support features like bulk messages to customers/leads.
  • automatically trigger messages via integrations & APIs.
  • multiple logins & support dashboard.

On the other hand, WhatsApp API comes with a lot of chat automation features. For instance, unlike WhatsApp Business App, WhatsApp API has no app or front-end interface and needs to be integrated directly into business software.


WhatsApp API can only be accessed via WhatsApp Business Solution Providers or BSPs.

WhatsApp Business API Solution Providers: BSPs

The WhatsApp Business API Platform is not available for everyone yet. Facebook has chosen 40-50 third-party solution providers to distribute WhatsApp Business API to every other business.


BSPs offer whatsApp APIs for businesses to build their solution on top of WhatsApp APIs. These BSPs can help you communicate with your customers using whatsApp APIs for the approved use cases of customer support and time-sensitive, personalized notifications.

WATI, as a WhatsApp API provider (BSP), on the other hand also provides you with a complete WhatsApp CRM with a dedicated Team Inbox to manage communications. You can just integrate it with your WhatsApp Business API number and you’re ready to use all the features of WhatsApp Business API directly via WATI.

The Components Of A WhatsApp Business Account

There are two major components of WhatsApp Business API:
1. WhatsApp Business Profile
2. Phone number

WhatsApp API for Business: Business Profile

A WhatsApp Business Profile provides customers with more information about your business. Businesses can optimize their business profiles by updating their cover photo, description, address, email, and website.
